HARDGROVE, OF BETHLEHEM, PENN-SYLVANIA, ASSIGNORS TO FULLER LEHIGH VANIA, A CORPORATION OF DELAWARECOMPANY, OF FULLERTON, PENNSYL- MEANS FOR RETAINING FURNACE WALL BLOCKSAGAINST TUBES Original application filed October 1927, Serial No.227,456. Divided and this application filed November '17, 1928.

This invention relates a furnace wall and blocks with means for keepingthe furnace wall blocks or tile in firm contact with water wall tubesvlocated in the furnace wall so as to maintain a good contact for thebest heat conduction between the tile and tubes, and yet provideattachment in such a manner that broken or injured blocks-or tile can beremoved and replaced by new ones. This is a division of our applicationSer. No. 227,456, filed October 20, 1927.

The invention will be understood from the description in connection withthe accom panying drawing in which Fig. 1 is a side View partly brokenaway showlng a port on of the furnace wall and Fig. 2 is a section alongthe line 2-2 of Fig. 1.

In the drawing reference character 1 indicates water tubes of thefurnace wall to which the water wall blocks or tile 2 are attached. Eachblock or tile 2 is somewhat T-shaped in cross section and is providedwith rounded portions or curved surfaces 3flto fit against the tubes,and with an extension 4 that projects beyond the centerlines of thetubes.

Holding members 5 have their ends welded to the tubes 1, as indicated at6. The members 5' are provided with transverse openings 7 into whichwedges 8 may be forced. Plates 9, preferably of resilient material areplaced between the holding members 5 and beneath the wedges 8, so thatwhen the-wedges are driven in, the edges thereof, contacting with theupper curved edges 10 of the plates 9, will force the plate toward thetile 2. Packing material 11 may be inserted between the plates 9 and thebacks of the tile '2.

Changes and modifications can be made without de artin from the spiritor scope of the invention. is to be understood that where the word tileis used in the specification and claims it is meant to include blocks aswell, that may be made entirely of metal, or composite blocks made ofmetal and refractory material.
